商品说明

1、概述
GW5型户外高压隔离开关是用于三相交流50Hz的户外高压电气设备,供线路在有电压无负载的情况下进行分合,以及对被检修高压母线、断路器等电气设备与带电的高压线路进行电气隔离之用,也可用于开合小的电容或电感电流。在闸刀处于正常分闸位置时,可提供一个符合安全要求的绝缘距离。 广泛使用于35-110kV变电站。
2、主要结构及特点
1、每台隔离开关单极由底座、两个支柱绝缘子、接线座、左右触头装配、 接地刀等部分组成;
2、触指与触指座之间采用轴窝连接,接线板与触杆之间采用铜软 连接,使产品的主回路电阻大幅度减小。
3、两只支柱绝缘子呈“V”型布置安装在同一底座上,具有占地面积小,减少安装金属构架的优点;
4、采用滚动轴传动,操作省力,转动灵活,开合自如。
5、通过伞齿轮转动,从而保证两柱的分合闸动作一致;
6、两支柱轴线交角50度,转动角度达90度,分闸后有足够裕量的绝缘隔离断口,从而 保证其安全性;
7、由操动机构的带动基座部拐臂、拉杆,分别使两支柱绝缘子 同步转动,以实现分合闸操作,
8、产品有不接地、单接地、双接地三种方式,主轴与接地之间有可靠的机械连锁,从而保证其安全;
9、配用CJ2自动操动机构或CS-17G手动机构等,可附装电磁锁。操作机构上的定位装置, 能保证触头与静触头的处于正确的接触位置或分断位置。
